Steven Snyder is running the lateral link relocation kit with Motegi MR-116 18×9 (45mm offset) & 275/35/18 BFG Rival tires under a stock 88 coupe body. Clearance to the trailing link is very tight, but it does clear.

For the LS4/F40 car I will eventually run 18 x 10 1/2" w/ 56 offset (S10 wheel bearing conversion) under the stock body, but it requires pulling the rear suspension in 1 5/8" at the bottom (shorter lateral links and axles) and 1" at the top (upper mount relocated - already done and one of the reasons I can't use the engine vent hold down brackets).

Nice work Paul!

I had to run a box to the post office over lunch, so I took the car to my normal WOT section of road and did a 7K up shift from 2-3 and it worked in quick fashion! It still takes some physical effort/momentary delay for the synchos to do their thing, but being able to shift it quickly from that RPM is a substantial improvement over the last cable setup. I think this shifter cable mod will help drop my ET a few tenths! Then get some better tires and do a driver mod and climb the 1/4 mile list a little further!

Awesome! I think I'll use the stock shifter then to start with, until I can get a more modern shifter designed and built for my car. That's at least one less thing I can avoid putting off for getting my swap done. Hopefully I'll have some more room in the garage soon and will be able to do some work on it.

Any news on the flywheels? It's one of the big items I still have to secure to be able to get my swap done. I'm sure it'll be months before I really need it, though. :-/

I will be travelling next week, but once I am back, I plan to resend the flywheel drawing for a new quote (old one is over 1 year old). I will have them make a single flywheel to verify that the drawing and their CNC program result in the proper flywheel shape/fitment. Once that is done, then I will order another 4 to start. I will keep the 1st one for the LS4/F40 swap I am starting and put the other 4 up for sale. Once those 4 are gone and depending on interest I will try to increase the order quality from 5 to 10. I will also have the starter bracket laser cut and a fixture made to weld it up.

So hopefully by September/October both the LS4/F40 flywheel and starter mount will be ready to sell.

Great. Consider one of those first four flywheels sold. Just PM me when you verify the flywheel is proper, and you're ordering them, and I'll send you the money/shipping info.

I'll sign up for the second set of parts, FW and starter mount. Just let me know when to send payment!

Once I have verified the first good flywheel from the shop, then I will most likely start a mall thread to alert people of their upcoming availability and to get a better idea of how many I should make with the initial run. Right now 4 of the first 5 flywheels have interested parties wanting them, so I may need to make 7-10 for the first production batch.

have you considered offering multiple bolt patterns for the flywheel? if the same flywheel would work for N*'s and 3800's, you could open up your market considerably.

I have. Once the LS4/F40 flywheels are available, I might have them make 5 or so blanks with the center bore to match that of the smallest crankshaft pilot (probably the 60 degree motors). Then I can bore the pilot and drill the crankshaft pattern on them here at the house on my vertical mill for adaption. The neutral balance engines (60 degree v6, N*, & LS4) are easy. The ones with a specific imbalance will be more complicated and will cost more, if I even decide to offer them.
